Patent DE-2132977-A1 (DE)
Title: Metal sheathed multicore cable - using single longitudinal bent tape and plastic outer sheath
Inventor: EILHARDT BERND
IPC: H01B9/02
Filed: 1971-07-02
Abstract: The edges of the strip are folded radially outwards to butt together, and the raw edges welded, soldered to seal the cable before the web so formed is bent down over the tubular profile of the sheath proper as in the parent patent. To improve the bending flexibility of the cable a longitudinal strand of plastic material e.g. polyethylene copolymer, is interposed between the sheath and the bent over web. A relatively thin coating of thermoplastic polymer which keys to the metal is then applied overall and finally a polyethyelen or PVC outersheath is extruded onto the cable.
Patent DE-2147411-A1 (DE)
Title: Anode rod clamps - automatically rotate in fastening/ unfastening sequence
Inventor: SPRINGER KURT
IPC: C25C3/16
Filed: 1971-09-22
Abstract: A clamp for fastening anode rods to the bus bar of an aluminium electrolysis tank is designed so that, when the locking screw is undone, the clamp automatically turns through 90 degrees to allow free access to the rod. After the new rod has been inserted, turning the clamp in a clockwise direction automatically brings it into the clamping position, and further turning of the shaft tightens it to hold the rod to the bus bar. Construction is lighter and cheaper than earlier designs using geared drives.
Patent DE-2150370-A1 (DE)
Title: Narrow stretch fabric prodn - stretch, non-stretch fabric sections have different weft counts on elastic warp
Inventor: GOFF JUN RICHARD E
IPC: D03D15/56
Filed: 1971-10-08
Abstract: A narrow fabric e.g. for brassiere straps has elastic sections and inelastic sections (or sections of reduced elasticity) having a higher weft count, on an elastic warp. A loom producing such fabrics has its fabric-forwarding roll driven at different speeds relative to the weft insertion rate, so that the inelastic sections have such a weft count that the extended elastic warp cannot contract.
Patent DE-2153591-A1 (DE)
Title: Hop granulate prepn - by cooling hop powder and compressing to pellets
Inventor: MUELLER ADAM DR
IPC: B01J2/24
Filed: 1971-10-27
Abstract: In Parent Patent, hop granulate is prepd. from hop powder by treatment in vacuo. In present modification, hop powder of 20-2000 av. grain-size and contg 1-8% water is cooled, e.g. to -1 to -40 degrees C, and then compressed to form pellets. In spite of cooling and solidification of hop resins at -1 to -30 degrees C good granulation of hop powder can be achieved without use of steam or water as binders and with preservation of hop bitter substances.
Patent DE-2153704-A1 (DE)
Title: Dough kneading machine - with spiral dough hook and central boss
IPC: B01F9/00
Filed: 1971-10-28
Abstract: The dough hook operates in the annular gap, just wider than its effective dia., so that the dough is forced onto it by the central boss at a constant rate. The boss is a truncated cone, with rounded top, and has >=1 axially parallel ribs faired into that top and into the bottom plane of the kneading pan. These ribs also assist in the aeration of the dough. The central boss is >1/2 the height of the pan and prevents the dough from forming a dead zone in the pan centre so improving the uniformity of kneading.

Title: District heating ejector type jet pump - controlled by sleeve between working medium inlet and collector nozzle
Inventor: BAELZ JUERGEN DIPL ING
IPC: G05D16/06
Filed: 1973-06-15

The control is effected by a movable nozzle element, shaped lika a hollow truncated cone, between the fixed central conical control stem and the seat of the collector nozzle. In its one extreme position, the passage between suction chamber and collector nozzle is fully open but the supply of working medium to the collector nozzle is cut off at the control stem. In other extreme position, the working medium can enter the collector nozzle but the access to the suction chamber is partly or fully cut off.

Title: Pneumatically or hydraulically operated lifting device - has lifting plate arranged above base plate with semi toroid casing between
Inventor: VAUGHEN JACK FRANCIS
IPC: B66F3/35
Filed: 1973-12-12
Abstract: Pneumatically or hydraulically operated lifting device where a lifting plate is arranged above a base plate and between these plates is a casing in the form of a semi-toroid which is fitted to both plates so that it can be pumped up to lift the lifting plate. A valve passes a pressurised fluid into the inside of the casing. The outer peripheral edge of the casing is air tight on one of the two plates and includes a first face. A ring-shaped centre section of the casing is fitted to the other plate and defines a second face, smaller than but symmetrical to the first face. The casing outer wall is inclined upwards on the second face and stresses in the diametrically opposite parts of the outer well limits lateral movements of the lifting plate relative to the base plate to stabilise the load. A similar condition exists between the second face and a third face.

Title: Magnetic core mounting for gas ignition safety unit - has yoke segments engaging projections on carrier plate
Inventor: KRAJC ADOLF
IPC: F23N5/10
Filed: 1973-12-14
Abstract: Magnetic insert is for a thermoelectric ignition safety unit for a gas-fired appliance, and has a U-shaped magnetic core whose yoke abuts a carrier plate, with projection(s) formed on the plate end face toward the core and engaging beneath a shoulder at the outer periphery of the yoke, to hold the core fast to the plate. The yoke has at least one shoulder segment, and the carrier plate has at least one corresp. local projection to hold the yoke to the plate. The peripherally measured length of the segment(s) and projections is such that the yoke can be set at a given angular setting on the plate, and then an angular rotation of the yoke brings the segments and projections into engagement like a rotary closure. The mutually abutting clamping faces of segment(s) and a projection, seen peripherally, have a rise w.r.t. the plane of the plate such that the yoke, after the rotation is self-locked on the plate and secure against shaking, but releasable without damage.
